Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes revising the hypothesis. carter runs a catering business. he wondered where he should chill sodas for an event: in the fridge, a cooler filled with ice water, or a cooler filled with ice cubes. he recalled that solids conduct heat better than liquids or gases, so he reasoned that the fridge should be the least effective, and the cooler with solid ice should be the most effective. to test his idea, carter opened nine bottles of soda and measured their temperatures. he put three in the fridge, three in a cooler with ice water, and three in a cooler with ice cubes. he checked the sodas temperatures every five minutes and compared them. the sodas in the fridge cooled the slowest, as expected. but surprisingly, the sodas in the ice water cooled the fastest! he realized that the solid ice did not touch the cans entire surface, while the ice water did. carter revised his prediction: encasing the sodas in a block of ice would cool them the most effectively, but it was more practical to use ice water. he shared his findings with his employees.

Explanation:

The part where Carter changes his initial prediction based on the results of his experiment is the revision of the hypothesis. He initially thought solid - ice cooler would be most effective, but after seeing that ice - water cooled faster, he revised his prediction to suggest encasing in a block of ice would be most effective but ice - water is more practical.

Answer:

Carter revised his prediction: Encasing the sodas in a block of ice would cool them the most effectively, but it was more practical to use ice water.
